Here's how much the top Wall Street banks have earned in fees this year

It has been a miserable start to the year for Wall Street dealmakers.

Revenues from equity and debt deals and mergers and acquisitions have fallen off a cliff. 

Industry-wide global investment banking revenue is down 36% from the first quarter of last year. Revenues are down in pretty much every single business line.

And JPMorgan has taken home the biggest chunk of a shrinking pie, according to Dealogic's preliminary league tables for the first quarter. 

League tables are a contentious subject on Wall Street.

Banks use them when pitching for new business, and a good ranking means serious bragging rights.

But the league table-data can also be sliced up to make a bank's performance look better (by narrowing the field very narrowly, for example).  

Though they're based on estimates, these tables are the broadest possible and a closely-watched indicator of who is up and who is down. 

Here's how the banks stacked up this time around.

JPMorgan tops the table for total investment banking revenues.

JPMorgan has a 8.1% market share and $1 billion in total revenues for the year to March 23. It is followed closely by rival Goldman Sachs, with $899 million and a 7.0% share. Bank of America was in third place, with $854 billion.

Global investment banking revenue was $12.8 billion for the period, down 36% compared to the first quarter of 2015.

JPMorgan tops the table for M&A too.

JPMorgan is top of the table for M&A too, with $511 million in revenues, narrowly ahead of Goldman Sachs in second, with $499 million. 

M&A revenue was a bright spot last year, but the market has slowed more recently. M&A fees are down 24% from the first year of 2015. M&A revenues across the industry stand at $4.4 billion, down from $5.8 billion.

And equity capital markets.

JPMorgan ranks top in equity capital markets too, ahead of Morgan Stanley and Goldman Sachs, which $187 million in fees. 

Total ECM fees are down more than 50%, dropping from $5.2 billion to $2.3 billion.
